title: Role of imaging in assessment of atrial fibrosis in patients with atrial fibrillation: state-of-the-art review.
abstract: Atrial fibrillation (AF) is the most common arrhythmia in the world. Despite the large number of studies focused on the causes and mechanisms of AF, it remains a clinical challenge. Atrial electrical and structural remodelling caused by AF is responsible for the perpetuation of the arrhythmia. However, a validated noninvasive method for assessment of atrial fibrosis in clinical practice is lacking. In this review, we aim to present an update about the origins and mechanisms of atrial remodelling, particularly focusing on atrial fibrosis, and compare imaging techniques that can detect atrial changes and greatly contribute to the clinical management of patients with AF.
